Hello FreeSurfer users,
I was finally able to compile mri_em_register successfully from source and trying to test the build with subject 'bert', I ran into this error
~/freesurfer/bin# ./mri_em_register -uns 3 -mask $SUBJECTS_DIR/bert/mri/brainmask.mgz $SUBJECTS_DIR/bert/mri/nu.mgz $FREESURFER_HOME/average/RB_all_2008-03-26.gca $SUBJECTS_DIR/bert/mri/transforms/talairach.lta aligning to atlas containing skull, setting unknown_nbr_spacing = 3 using MR volume /usr/local/freesurfer/subjects/bert/mri/brainmask.mgz to mask input volume... reading 1 input volumes... logging results to talairach.log reading '/usr/local/freesurfer_4_5_0/freesurfer/average/RB_all_2008-03-26.gca'... average std = 6.9 using min determinant for regularization = 4.7 0 singular and 1812 ill-conditioned covariance matrices regularized reading '/usr/local/freesurfer/subjects/bert/mri/nu.mgz'... znzTAGskip: tag=-8454144, failed to calloc 4286513152 bytes!

Has anyone had similar error before?
I'm using Ubuntu 10.04 LTS- 64 bit and I've built mri_em_register from scratch using CVS public checkout "-P dev" The test subject was through installing freesurfer 5.1.0 and also same has happened with freesurfer 4.5.0
Any help with this would be again greatly appreciated!
Cheers!
